• Alt/Shift key not released after switching keyboard layout

  - by szx

  Sometimes when I switch layout using either Alt+Shift or Ctrl+Shift the Alt key is not recognized as being released thus if I press e.g. F a File menu opens up. Last time that happend I lost all data I filled into a text form on a webpage because I pressed the Home key while typing and Firefox suddenly went to my home page! Moreoever, it still remains unreleased after hundreds of keypresses like if I'm holding it! Same goes for the Shift key. I would rather file a bug at Launchpad if I could but I have no clue what fucking package name should I type in the ubuntu-bug command! Have anyone else had this issue? Can you suggest a solution or maybe another place to report this bug?

• Why does the Git community seem to ignore side-by-side diffs

  - by Kyle Heironimus

  I used to use Windows, SVN, Tortoise SVN, and Beyond Compare. It was a great combination for doing code reviews. Now I use OSX and Git. I've managed to kludge together a bash script along with Gitx and DiffMerge to come up with a barely acceptable solution. I've muddled along with this setup, and similar ones, for over a year. I've also tried using the Github diff viewer and the Gitx diff viewer, so it's not like I've not given them a chance. There are so many smart people doing great stuff with Git. Why not the side-by-side diff with the option of seeing the entire file? With people who have used both, I've never heard of anyone that likes the single +/- view better, at least for more than a quick check.

• Is it safe to set FPS rate to a constant?

  - by Ozan

  I learned from game class that in update function, every movements must be time dependent for the sake of linearity in movement. We made a simple game. Every move like going left, right or jump is written time dependent. But, in some other computers, our game is worked very differently. For example, our character jumps higher than it should be. I guess this is because each computer has different FPS rate according to its specification. My question is that what should we do to make this game work in same way in every computer? Setting FPS rate to a constant is a solution?

• Getting data from a webpage in a stable and efficient way

  - by Mike Heremans

  Recently I've learned that using a regex to parse the HTML of a website to get the data you need isn't the best course of action. So my question is simple: What then, is the best / most efficient and a generally stable way to get this data? I should note that: There are no API's There is no other source where I can get the data from (no databases, feeds and such) There is no access to the source files. (Data from public websites) Let's say the data is normal text, displayed in a table in a html page I'm currently using python for my project but a language independent solution/tips would be nice. As a side question: How would you go about it when the webpage is constructed by Ajax calls?

• InputLayout handling

  - by Kikaimaru

  Where are you supposed to store InputLayout? Suppose i have some basic structure like. class Mesh { List<MeshPart> MeshParts } class MeshPart { Effect Effect; VertexBufferBinding VertexBuffer; ... } Where should I store input layout? It's a connection between vertex buffer and specific pass, i can live with just 1 pass but I still have diffferent techniques so i need at least an array with some connection to effecttechniques, but I would appriciate something not crazy like dictionary. I could also create wrapper for Effect and EffectTechnique, but there must be some normal solution.

• How to avoid “The web server process that was being debugged has been terminated by IIS”

  - by ybbest

  Problem: When debugging asp.net by attaching w3wp.exe process, you often will see encounter the following error message, the web server process that was being debugged has been terminated by IIS. Analysis: This caused Internet Information Services (IIS) to assume that the worker process had stopped responding. Therefore, IIS terminated the worker process. Solution: 1. Open IIS manager. 2.Click application Pools>>select the application pool associated with the site>>and click Advanced Settings 3. Click Advanced Settings of the application pool and set the Ping Enabled property from True to False. Now, reattach the process from Visual Studio, you should not get the error message.

• Intercepting the Unity logout

  - by qbi

  I want to copy some data from another machine to a local computer on a regular basis. At the moment I'm researching different solutions and try to find the one which fits best. Basically I want to open a network connection (or use an existing one), make a VPN connection and start a rsync process. This should be done on every logout of my desktop session or on shutdown. One possible solution might be to somehow intercept the Unity shutdown and execute a script. So is there a possibility to execute a script on GNOME/Unity shutdown? I'm aware that you can do it on system shutdown. How can I do this?

• What is the traditional way to maintain extensibility in a database-driven application like this?

  - by Jsess

  I'm working on a simple application for a game in Java that allows a user to record whether they have collected a given item and how much experience it contains. This will work for multiple item types (weapons, armor) and each will have its own tab with a list of all items that qualify under it. Making changes as new types are added is not such a big deal (if a clothing slot is added, for instance), but new items are added to the game all the time in biweekly patches, and I'm not sure what the traditional/customary way to make sure the application is user-extensible without requiring me to would be. Whether that would be adding a configuration menu that allows users to add news items (new rows to the local SQLite database) or a text file with something similar, but I'm certain there's a well-accepted way to do this that I'm not aware of. I'm new to databases and ignorant of the solution, so what's the professional/futureproof way to do this?

• AdventueWorks Design Patterns Project - Part 1

  - by RonGarlit

  This is the presentation I did tonight at PHILLYNJ.NET.  It is the first in a multi-part of a series on the Applied Design Patterns.   The solution files are working code with design pattern notes in the comment blocks. After the overview and higher level discussions on Enterprise Design Patterns I reviewed the low level Database Access Library of code.  With walk-throughs of the the code and unint test. After that we went through the ProductPhotoConsoleTest Application that performed intergration testing of the DBAccess Class with the AdventureWorks ProductPhoto table extracting the photos and writing them to a file folder. The Demo code and PowerPoint can be obained from this link.  https://skydrive.live.com/?wa=wsignin1.0&cid=29e34e9a8650bb9e#!/?cid=29e34e9a8650bb9e&sc=documents&id=29E34E9A8650BB9E%21151 Please note that I use Visual Studio 2010 Ultimate.  If you have a lesser version the Modeling projects likely will not work or have limited functionality and you should unload that project to prevent warning. Enjoy! --Ron

• 3.5.0-18 kernel update broke BCM43228

  - by ignition

  After updating the kernel to 3.5.0-18 the Broadcom BCM43228 wireless card of my Acer Aspire One 756 has stopped working properly. The card often refuses to connect to my AP, and if it connects it behaves very unstable. I have already reinstalled the drivers, as recommended by googling around. As far as I can tell the only driver that supports my card is the bcmwl package. I found one solution saying I should install broadcom-sta using module assistant, however I could not get this to install and apparently broadcom-sta and bcmwl are effectively the same driver? Is anyone experiencing similar issues? Is it possible to just downgrade to the previous kernel version?

• How should I set up UDK with Git and CruiseControl?

  - by Martin Sojka

  For a new project in UDK, I'd like to set up a Git repository for version control and a CruiseControl.NET-based continuous integration solution. The good news is that he first part seems easy enough and CruiseControl.NET can work off Git repositories. The bad news is that according to my searches, nobody has ever tried to do this. Ideally, I'm looking for a step-by-step guide on how to set up such a development environment assuming more than one development computer, one central repository for the "master" branch, and one machine for building and packaging the binaries via CruiseControl.NET. Related: Version control system for game development with UDK? Options for UDK and version control repositories? CruiseControl.NET and Git

• Immutable design with an ORM: How are sessions managed?

  - by Programmin Tool

  If I were to make a site with a mutable language like C# and use NHibernate, I would normally approach sessions with the idea of making them as create only when needed and dispose at request end. This has helped with keeping a session for multiple transactions by a user but keep it from staying open too long where the state might be corrupted. In an immutable system, like F#, I would think I shouldn't do this because it supposes that a single session could be updated constantly by any number of inserts/updates/deletes/ect... I'm not against the "using" solution since I would think that connecting pooling will help cut down on the cost of connecting every time, but I don't know if all database systems do connection pooling. It just seems like there should be a better way that doesn't compromise the immutability goal. Should I just do a simple "using" block per transaction or is there a better pattern for this?

• HTTP(S) based file server

  - by Michael

  I've got a server running Ubuntu 10.04. I've already gotten openssh for ssh and sftp on it. I've been looking for a web-based (http, or preferably https) file server, perhaps a web-front-end to an (S)FTP server, that allows access to a specific folder, and also allows uploads. It requires user authentication, preferably using PAM. This web-based solution is for users that are not allowed to use FTP software / browser extension and don't have flash / java browser plugins within their corporate environments. So far I have looked into: Webmin: Includes a file manager, however it uses Java, and I'm looking for a plugin-free implementation. Apache2: I was able to set up https and PAM authentication, but the barebone implementation doesn't include file upload (as far as I'm aware of). HFS: Haven't tried it out because it is for Windows/wine only, and I don't want to run it under wine.

• How to reverse file ownership and permission settings

  - by pandisvezia

  I installed LAMP and WordPress on my system a week ago. Since I couldn't create Child Themes in WordPress and work with PHP folders for my other projects collocated in var/www without using Nautilus I wanted to solve the permissions issue. I hoped to bring a solution carrying out the commands on this page for my WordPress folder: http://wiki.apache.org/httpd/FileSystemPermissions. This allowed me to play with any file in the folder like creating and modifying .css files through WP Admin, etc. But after a restart I discovered that I can't change DNS settings of my network connections in the list anymore because it is asking me the root password and even though I enter the password it doesn't let me do the action giving "insufficient privileges" error. Can you help me correct the mistake I possibily made during the configuration and, maybe, configure again the permission and ownership settings for var/www/somefolder as it is adviced to be configured under general circumstances? Thanks in advance!

  I am using both Windows 7 and Ubuntu 11.10 on a single system with the same hardware. While I'm making call through Gmail or Skype my voice is audible to others while I'm on Windows 7, but while I'm on Ubuntu 11.10 it's not audible to others, but I am able to hear their voice. But while I'm playing music on Ubuntu along with a call, the others are able to hear the music, but my voice is not audible for them. Please give me a solution for this and tell me where I can change the microphone settings on Ubuntu 11.10.

• Atheros AR5BWB222 Wireless Intermittent Connectivity

  - by Bart

  So I recently installed Ubuntu on my Acer Aspire V3-551 laptop. I have an Atheros AR5BWB222 wireless adapter. Everything works fine except for the wireless. I can sometimes connect to the wireless, but most of the time it will be making an attempt to connect and then enver connect. Or it will connect, but it will only stay connected for about 10 seconds before getting disconnected from the wireless. All the other drivers updated through System SettingsAdditional Drivers are fine, even the Ethernet. Its just the problem with the wireless. I've tried a power managment setting, tried looking for additional updates, but nothing fixes my problem. Is there any solution for my particular wireless card?

• What is an effective way to organize tasks for a new project?

  - by Dulan

  Is there a practical solution to organizing the initial tasks for a new project? To elaborate, imagine the features/stories/goals are laid out for a project. How might one go about organizing those into sane tasks for the first few versions? The scenario I typically have in mind has the features listed as a high-level reference for what the end user-experience should involve. The tasks for constructing such features are then broken down into chunks (such as "create interface for X component"). Such a task is not necessarily "tied" to only that feature and may be useful when building subsequent features. Is breaking features down into small, code-able solutions valid? Or should they be slightly removed from any specific implementation? I do not expect that there is one "right" answer to this question, but I am looking for a fairly pragmatic and unobtrusive approach. As a note, I'm looking for solutions that are independent of any tools or "systems" used for managing the tasks themselves.

• Faut-il en finir avec la mode NoSQL ? Ou est-ce plus qu'une simple mode passagère ?

  Faut-il en finir avec la mode NoSQL ? Ou est-ce plus qu'une simple mode passagère ? La question est volontairement provocante. Elle est posée, en des termes encore plus crus, par Ted Dziuba dans un billet intitulé « I Can't Wait for NoSQL to Die ». « Certains ingénieurs pensent que l'évolutivité et l'architecture sont la solution [de tous les problèmes]. C'est comme cela qu'est né le mouvement NoSQL », y écrit-il. « L'idée développée avec NoSQL est que toutes les bases de données relationnelles, telles que MySQL et PostgreSQL, sont caduques et que les bases de données fondées sur des documents ou les bases de données sans schéma représentent l'avenir». ...

• How can I compile an IP address to country lookup database to make available for free?

  - by Nick

  How would I go about compiling an accurate database of IP addresses and their related countries to make available as an open source download for any web developer who wants to perform a geographic IP lookup? It seems that a company called MaxMind has a monopoly on geographic IP data, because most online tutorials I've seen for country lookups based on IP addresses start by suggesting a subscription to MaxMind's paid service (or their less accurate free 'Lite' version). I'm not completely averse to paying for their solution or using the free one, but the concept of an accurate open source equivalent that anyone can use without restriction appeals to me, and I think it would be useful for the web development community. How is geographic IP data collected, and how realistic is it to hope to maintain an up-to-date open version?

• How to write efficient code despite heavy deadlines

  - by gladysbixly

  I am working in an environment wherein we have many projects with strict deadlines on deliverables. We even talk directly to the clients so getting the jobs done and fast is a must. My issue is that i'd always write code for the first solution that comes to my mind, which of course I thought as best at that moment. It always ends up ugly though and i'd later realize that there are better ways to do it but can't afford to change due to time restrictions. Are there any tips by which I could make my code efficient yet deliver on time?

• Window controls missing; Cannot maximise or minimize applications

  - by omg_scout

  Ubuntu 12.10 32 bits, fresh installation. How can I make Unity maximize or minimize a window? I see no button,option, anything, do I miss something big? Quick googling did not give me a piece of answer, too: On first screen, I have a terminal window. Only clue about maximizing it I found was pressing F11 which made it fullscreen, hiding left bar as well. I would prefer it to take whole free space instead of whole screen. How can I do that? On second screen, I have an opera browser which takes bigger part of the screen but I can't make it take whole screen. Restarting opera did not work. How do I minimize/maximize apps? Also, in case I would like to see the desktop, only solution I found was closing everything Help guys. I kind of like new GUI, but I can't have simplest tasks done there, I feel like I miss something big there.

• How can i get almost pixel perfect collision detection in a multiplayer game?

  - by Freddy

  I'm currently working on a multiplayer game for iPhone. The problem i have, as with all multiplayer games, is that the other user will always see everything at a non-constant delay. The game I'm making need to have a almost pixel perfect collision detection, but 1 or 2 pixels off is not that big of a deal. How can I possibly get this working? I guess I could just set local player to also be at X ms delay. However this will probably just be worse and feel sloppy when the user input. I know this problem is probably something network programmers deal with everyday and I would be glad if someone could give me a possible solution for this.
